DRAWER-TYPE cons-oven.

To all whom it may concern Be it known that I, ARoIImALD M. LOUDON, a citizen of the United States, residing at Elmira, in the county of Chemung and State of New York, have invented a certain new and useful Improvement in Drawer-Type Core-Ovens, of which the following is a specification.

This invention relates to core ovens provided with a plurality of drawers for the cores, each slidable into and out of the oven, independently of other drawers and other parts of the device.

The object of this invention is to provide an oven of this type in which the supporting devices are so arranged that one or more drawers may be partially or wholly with drawn from the oven, each entirely independently of the other and still be so supported as not to interfere with the free access of workmen to the drawer or drawers of .an

adjoining oven for the purpose ofeither' inserting or removing cores or other materials therefrom.

The invention consists of a device capable of carrying out the foregoing objects, which can be easily and cheaply made, and is satisfactory in operation and not readily liable to get-out of order.

The invention further consists in features and details which will be more fully set forth in the specification and claims.

Referring to the drawings, Figure 1 is a side view takenzon the line 11 of Fig. 3, illustrating the preferred form of this device. Fig. 2 is a front view of two sections of the oven of this invention, the left hand half being taken on approximately the line 2-2 of Fig. 1 and the right hand half being taken in full front view or at the extreme Fig. 3 is a sectional view on the line 33 of Fig. 1. Fig. 4 is a plan view on the line 4-4 of Fig. 1. 4

Again referring to the drawings in whic similar numerals indicate the same parts throughout the several views, we see particularly in Figs. 1, 3 and 4 the ordinary rear wall 10, side .or intermediate walls 12 rising from a base 16 below which are located heat flue 18 and draft flue 19 of the ordinary type and construction. The side and rear walls are closed at the top by the member 20 supporting suitable smoke flues 22.

The walls and cover heretofore mentioned Specification of Letters Patent.

form in connection with the base 16 a furnace chamber or receptacle 24 closed by a front plate 26 removably secured in position as shown in Figs. 1 and 2 by any convenient form of fastening devicesuch as the cleats or buttons 30 adapted to be held rigid by bolts or rods 32 in the ordinary manner. Each front plate 26 is provided with a plurality of horizontally elongated openings 34 one above the other, through which drawers 36 designed to receive cores or the like, may move into and out of the furnace or oven in the ordinary manner in which a drawer of a bureau, cabinet or the like acts. The problem solved by this invention is to so mount these drawers that when anyone of them is drawn out as described to the position of the middle one in Fig. 1, workmen may have ready access to it for the purpose of inserting and removing cores or the like therein, while at the same time the drawer remains in horizontal position so that the contents do not spill out and also to so arrange it that the external support for a drawer is not in the way of access to a drawer withdrawn in an adjacent bank or case of drawers.

The foregoing difficulty is solved by mounting the drawers so that they are supported at their rear ends on two rollers 38, located at substantially the extreme side edges of the drawer as clearly appears in Figs. 3*ancl 4, and at their front ends upon a single roller 40 located at approximately in the middle of the front of the drawer so as not to be in. the way of a workman approaching the partially or wholly extended drawer in a diagonal direction at the front outside corners or from the sides, and so that the contents of the drawers may be readily withdrawn from the notches 41 in the sides of the drawers. In order to carry out this object, it is necessar that respective wheels or, rollers just cribed be supported on suitable horizontal tracks. This is accomplished by having each side roller, 38, travel upon a horizontal track 48, of any convenient form, in the particular I "drawer plates 58, which are, as shown, of a greater size than the openings 34 so that when drawers are within the oven, these drawer plates close the openings leading into the oven through which the drawer travels, whereby, when all of the drawers are in the oven, the front of the oven is closed so that heat within the oven has no ready opening or escape. Similarly a block or plate 60, is provided at the rear of each drawer of sufficient size to substantially close the opening 34 through which that particular drawer travels when'the drawer is withdrawn to the position shown in Fig. 1. By this construction any drawer may be Withdrawn for loading or unloading while leaving the oven itself in a closed condition.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. In a device of the class described, the combination with an oven receptacle having an opening through which a drawer may be inserted and withdrawn, a drawer for said opening, track members along the/insides of the oven adapted to supportthe side edges of said drawer, and a track extending from the center of the oven on which the front portion of the drawer is supported in all its positions, said last mentioned track being the only device in front of the oven receptacle for supporting the drawer'a's it is withdrawn, for the purposes set forth.

2. In a device of the class described, in combination with an oven receptacle having a plurality of openings one above the other within which drawers may be inserted and withdrawn, a plurality of drawersone for each such opening, a supporting track for each drawer on each side of the inside of the oven for supporting the sides of the drawers movers in all positions of their movement and a corresponding number of parallel tracks one above the other, one for eachdrawer'extending from the center in front of the oven, adapted to support the respective fronts of the drawers in all positions, said last mentioned tracks being the only devices in front of the oven receptacle for supporting each ofthe drawers as it is withdrawn, for the purposes set forth.

3. In a device of the class described, in combination with an oven receptacle having an opening through which a drawer may be inserted and withdrawn, roller near the inner rear corners of the drawer, track members within the oven receptacle on which said rollers travel, a roller at approximately the center of the front of the drawer, and a track extending from the center of the oven set forth.

4. In a device of the class described, in combination with an oven receptacle having a plurality of openings within which on which said roller travels, for the purposes drawers may be inserted and withdrawn, a

plurality of such drawers, one-for each such opening, a lurality of tracks, one above the other withln the receptacle for supporting the sides of the drawers in all positions of their movement, and a corresponding number of parallel-tracks, one for each drawer, extending from the center of the front ofthe oven adapted to support the respective fronts of the drawers in all positions.

5. In a device of the class described, in combinationwith an oven receptacle. having openings for independently movable drawers, a drawer for each such opening, rollers upon the sides and near the rear ends of said drawers, parallel tracks within the oven and along the sides thereof, one for each such roller, a roller located at the center ofthe front of each drawer extending outside the oven, and atrack for each such roller suitably supported to extend in front of the oven, for the purposes set forth.

In witness whereof, lihave hereunto sub-- scribed my name-in the presence of two witnesses.
